LOS ANGELES – One of Hillary Rodham Clinton’s top aides threw a hissy fit over the high costs of a extravagant Hollywood fund-raiser – which laid an egg by netting the Senate campaign a paltry $57,820, it was revealed in court yesterday.

Ray Reggie, the brother-in-law of Sen. Ted Kennedy, testified at the trial of Clinton’s then-top fund-raiser, David Rosen, that Clinton aide Kelly Craighead was upset after touring the site of the upcoming gala event in August 2000.

When Craighead and Rosen returned to a swanky Los Angeles hotel, they argued “pretty hard” about lavish aspects of the fund-raiser that was by then just days away, said Reggie, who got involved in raising cash for the campaign at the behest of then-President Bill Clinton.

“Kelly was concerned about how much money was going to be made at the event,” Reggie testified in Los Angeles federal court.

“She kept asking, ‘How much are we going to make in this event, how much is this costing, why is this event so big?’ ”

Rosen, who is charged with grossly understating the gala’s costs, told her, “I’m the fund-raiser, I’ve got it under control,” recalled Reggie.

Reggie, who is facing unrelated corruption charges, secretly recorded Rosen talking about the fund-raiser in 2002 in an effort by the feds to get Rosen to make incriminating statements. But the recording was not put into evidence at the trial.

Rosen’s ex-girlfriend, Melissa Rose, who worked on the campaign, yesterday testified that Rosen and Craighead had a “tense conversation” after the walk-through.

Not only did the event turn out to cost way more than what was reported to the Federal Election Commission, prosecutors charge, it also raised peanuts for Clinton’s ultimately successful run for a Senate seat representing New York. The campaign reported the event cost about $400,000 to put on, but some estimates have suggested the real cost was $1 million to $2 million.

Whitney Burns, a campaign worker, testified the Hollywood event netted just $91,000 in so-called “hard money,” of which $57,820 went to Clinton’s campaign.

The feds have said Rosen understated the fund-raiser’s real costs to avoid the Clinton campaign being forced under election laws to spend a lot of hard money to cover gala expenses, rather than using it directly for Clinton’s campaign.

Reggie yesterday said he frequently asked Rosen how much the event was going to raise and how much it cost, but the fundraiser only answered, “It’s going to be great, it’s going to be a wonderful event.”
